Generic Adaptive Family, can it be hosted on a topography?

[HaiderAlghifary]

In a Generic Adaptive Family, is it possible to make the Point Elements snap on topography?

No; however, there are several ways to work around that

Option 1:

convert the geometry to a massed surface/face (various ways to do that) which you can divide and add nodes onto which an adaptive component may be hosted

Option 2:

Use an entourage family which can be hosted on Topography (an empty family with a vertical model line), then use that entourage family to host the adaptive placement points to (at the tip of the line)

I´m using railings for topography hosting and being adaptive to. This way, I can have some railing roads following it´s slope, for example 🙂

That´s a weird way to work with, but is functional.

The ways I know of are

- Exporting to DWG and reimporting - good solution, thanks for pushing me towards "faces"

- Working with mass forms - turning the topography to an exact replica seems not be doable from what I know. Please correct me if I am wrong.

Any other ways you could tell?

Great workaround!

Thank  you for the other post. I learned some things there too.

Can you please elaborate the "adaptive" part in the railing family?

Also, please show a screenshot of how you created railing roads. I would like to see how precise they can be.

Typically you would need a model line family and host your adaptive to the model line host. That way, you can host the model line circle to topo and your adaptive will follow with the topo surface.

Good tip, that's what DR.RD suggested in his Option 2.

You can do it using dynamo...

1.  Generate a mass surface from a toposurface ... I have posted a graph some time ago in this forum which does exactly that
2. You can also use dynamo to generate a grid of points on the toposurface and host the entourage line family onto these points. In this case you no longer need to convert the topo to mass

Could you please help me locate this post? I spent quite some time digging but failed to find it 😞

Why can't all fencing / railing manufacturers create all their BIM Models as Revit Projects instead of Revit Families, for this exact reason. I need a barbed wire fence, to host to topo, and everything i find online is a family, which cannot be hosted to topography defeating the need for the BIM model entirely. If Railings were able to made as their own RFA that would be great as well. However I encounter this problem all the time in creating Site renderings with fencing.
